MACHINE FOR MAKING VENEER BARRELS.

SPECIFICATION forming part of Letters Patent No. 708,633 dated September9, 1902. 1 Application filed June 21, 1901. Serial No. 65,532. (Nomodel.)

To all whom it may concern:

Be it known that I, WILLIS 0. GRANT, a citi-- zen of the United States,and a resident of Ash- Iabula, county of Ashtabula, State of Ohio, haveinvented certain new and useful Improvements in Machinery for MakingVeneer Barrels, of which I hereby declare the following to be a full,clear, and exact description, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in machinery for making veneerbarrels; and the objects of the invention are to provide a devicewhereby barrels can be constructed from nnjointed veneer staves and madeeither bilged or straight at the option of the maker.

My invention consists in the radially-extensible and sectional formerwith the accompanying mechanism for compressing the barrel staves andhoops thereon asthe barrel is being formed, for extending the sectionsof the former, and for withdrawing the same for rotating the barrel, andin the combination and arrangement of the various parts and constructionof the various details, as hereinafter described, shown in theaccompanying drawings, and specifically pointed outin the claims.

In the accompanying drawings, Figure l is an end elevation of my device.Fig. 2 is a front elevation thereof, the lever 13 being omitted. Fig. 3is an enlarged vertical cen-,

tral section of a bilged former. Fig. 4 is an end view of the same. Fig.5 is a side elevation of an annular former provided with straight sides.Fig. 6 shows a modified form of compression device, showing it adaptedfor a straight-sided barrel in solid lines and its adaptation to abilged barrel shown in dotted lines. side and end elevations ofthebarrel, respectively.

In the views, 1 1 are the four segmental portions of the sectionalbarrel-shaped former. These sections are supported upon pins 2, whichslide in the arms 3 of the spider 4 and in turn are pivoted upon arms ofbell-cranks 5, which are pivoted upon the short rods 6, which areinserted in the overhanging extremities 7 of the spider-arms and areadjustably set thereon by means of clamping- Figs. 7 and 8 showsectional nuts 8. The lower extremities of the bellcranks are pivotedupon sleeves 9, which movefreely upon the central sleeve 10, towhichthespidersarerigidlysecured. Splines 11 turn the sleeves 9, towhich the bell-cranks are-pivoted. A clutch at 1 2 is formed upon one ofthe sleeves 9 at one end of the machine, operated by the lever 13 andpins 14, and the sleeves at each end of the machine are connected by rod15, so that their movements will be simultaneous, and the bell-cranks ateach end of the machine are so arranged as to expand or contract theformer alike.

I Within the long sleeve 10, upon which the former is supported, isplaced a central shaft 16, mounted in bearings 17 17 atone extremitythereof, so as to support the former from one end. The sleeve 10 issupported thereon by means of reducing-nuts 18 at either end andretained in position by means of collars 19 and set-screws 20.Bevel-gears 21 and 22 may be used to drive the sleeve 10 at a slowspeed, or the former may be turned by hand, if desired.

Above the former is shown a roll 23, arranger] to compress the hoopsupon the exterior of the staves forming the barrel as it is formed. Thisroll is swung from an upper pivot-rod 24 by means ot links 34 and isprovided with grooves 25, in which the hoops are confined while beingplaced in position on the exterior of the barrel. Supports 30 are shownat either end of the rod 24. Grooves 26 are shown on the exterior of theformer-sections at either end, in which are laid the hoops, which areattached to the inside of the barrel at either end, and segmentalannular rings 27 retain the hoops at the ends of the barrel. As shown inFig. .6, the roll which retains the hoops upon the barrel whileundergoing the process of construction may be divided into as manysmaller rolls or sections as there are hoops. Each roll, asat 23, issupported in a separate bearing 28, which is adj ustably secured to across-bar 29 by means of clampingnuts 31 or by any other suitable means,this detail not being important to the invention. The bar 29 is thenswung from upper supports similarly to the first-mentioned roll 23.

To move the swinging roll 23 to and from the periphery of the former tocompress or release the barrel, I employ a positive form of device, asshown in Fig. 1, where 33 represents segmental racks secured to theswinging links 34 and arranged to engage the pinions 35 upon a shaft 36,to which are also secured the crankarm 37 and ratchet 38. A pawl 39 uponone of the supports 30 enables the operator to place the barrel undercompression and retain it there while busy with the construction of thebarrel.

In Fig. 5 is shown a former provided with straight sides. Upon thisformer sectional rings R can be secured, as shown in dotted lines, thusadapting it to a bilged barrel. In Fig. 6 also are shown in dotted linesrolls increasing in size from the center of the barrel position outward,adapted for use with a bilged barrel.

Figs. 7 and S are views of a barrel formed by this machine. Here 40represents the unjointed or straight staves, which separate in a bilgedbarrel at the center, but come together at their ends. Since veneerstaves are too thin to croze to receive the barrel-heads, hoops 41 mustbe secured within the barrel at either end, and hoops 42 are addedoutside the heads 43, thus completing the barrel. If desired, the stavescan be placed in double overlapping rows, so as to cover the openingsbetween the staves, and thus construct a tight barrel.

In constructing the barrel the inner hoops are first placed in thegrooves at either end of the sections, a stave is placed over thesehoops, the hoops are placed on the outside, and the roll above is swungdown to retain the parts together while the stave is nailed to thehoops, the nails clenching upon the metal underneath. The former is thenrotated far enough to make ready for another stave, and this is nailedin place, the process being continued until the circle of the barrel iscompleted.

The advantages of this device are great, since the staves do not need tobe jointed. Being thin and flexible they are easily placed in position,and scrap or material of irregular widths can be utilized for thepurpose, thus greatly reducing the cost of material and of the finishedproduct. The sections can be made to travel in and out radially as thebilge of the barrel requires, or if there is no bilge the travel need bevery slight. If the last stave or staves inserted do not fit, a littlecan be trimmed oif, thus avoiding the usual necessity in having stavesof exact width prepared before commencing a barrel.

The staves may be single ply or double or of as many thicknesses asdesired.

At one end of the machine one of the bearings 17 is formed in the leverL, which can be dropped to release the completed barrel. This lever ispivoted to the frame at Z, and the outer end is inserted in a keeperwhen the lever is used to support the barrel.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. In combination, a barrel-shaped former divided into segmentalsections, a main central sleeve passing longitudinally through saidformer, spiders provided with spider-arms and secured to said sleeve,pins passing radially through said spider-arms and secured individuallyto said sections, one at either end thereof, short movable sleeves onthe main sleeve, bell-cranks pivoted upon the spiderarms, and with theirarms severally pivoted to said short sleeves and to the before-mentionedpins, connecting-rods between the short sleeves, a clutch engaging oneof the short sleeves, and a main supporting-shaft within said mainsleeve, and means for rotating the sleeve, as described.

2. In a machine for the purpose described, comprising a formerlongitudinally divided into sections, a central supporting shafttherefor, mounted upon bearings at one end of the former, a main sleeveloosely mounted thereon and secured from longitudinal movement, meansfor extending and supporting said sections consisting of spiders securedto said main sleeve, bell-cranks pivotally secured to said spiders,short sleeves upon the main sleeve, to which the lower arms of thebell-cranks are secured, and pins mounted radially in said spiders andsecured to said sections at their upper extremities and pivoted to thebell-cranks at their lower extremities,connecti ng-rods between theshort sleeves and a clutch upon one of the short sleeves, means forrotating the main sleeve, means for retaining the outer and inner hoopsupon the former while the barrel is being constructed, and a temporarysupport for the face extremity of the shaft, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIS U. GRANT.
